Different grades of cement and their applications?
in a simple way it is the strength of concrete, which it can bear the loads of its specified grade ex C 25 grade can resist the weight of 25kn/m2 after 28days of 60% after 7 days.
What stronger brick or cement?
http://simscience.org/cracks/advanced/concrete2.html A common mistake people make is to use the words cement and concrete interchangably. It is important to remember that cement is only a component of concrete and concrete is the structural material. The cement used in concrete is not used as a building material because it would be too expensive and not as strong as concrete. So when you see a parking garage, a driveway, a sidewalk or a road remember it is made of concrete, not cement. And, by the way, that funny looking truck is a concrete mixer, not a cement mixer! But, if cement is not concrete, then what is it? Cement is a general name for a material that binds other materials together. Yes, it is another name for glue. There are many materials which we would classify as cements and they are usually identified with certain uses, and can produce different types of "concrete". The type of cement used to make the riding surface of some of our roads (blacktop!) is called asphalt cement. It is a petroleum bi-product, and it binds rock into the road material we call asphaltic concrete.
What is green cement?
Cement is called green when it is just poured. It is "green" until it sets up and cures or dries. This will vary depending on conditions. Wet cement has a slight green cast to it that changes to gray when it dries.In addition to consuming considerable amounts of limestone, sand and energy, producing each ton of Portland cement releases one ton of carbon dioxide into the environment. One of the emerging concrete technologies for sustainable development is to use "green" materials for construction. The "green" materials are considered as materials that use less natural resource and energy and generate less CO2. They are durable and recyclable and require less maintenance.
What does a yard of concrete cost in tn?
It would depend on two factors.. 1. are you mixing the concrete your self or 2. are you buying the concrete pre-mixed Mixing your own concrete by com-binding sand and cement is the way to go as its cheaper. Also by your sand in large loads as again its much cheaper than buying bags. If you want more in-depth answer sent me a message on my website.
What is the cement render mix ratio for external concrete block walls?
A good mix for rendering is 1 part lime 1 part cement and 6 parts sharp sand(1:1:6). To ensure a good even mix the materials should be measured in buckets rather than shovels, this will ensure consistency throughout the job. Water should be added in small quantities to the mix, the consistency should be just stiff enough to stand on the trowel. The area to be rendered should be brushed down with a stiff brush, then doused with a hose pipe to remove the rest of the dust and prevent the surface 'sucking' the moisture out of the render. Always start at the top and work your way down and protect the floor with with boards or sheets as it is quite a messy job. It is advisable to apply in two coats, the first coat should be 'combed' before it begins to set.This is done with a special rendering comb. The second coat can be a little weaker, i.e 1:1:8. Dont worry about any imperfections in the finish as these can be scratched off the following day with a trowel to achieve a lovely even finish ready for painting. Its my opinion to use a ratio of 4 sharp washed sand to 1 part cement, Bycol added to the water to aid in the flow of the cement but its not that important once your skill level is up there. Lime is not necessary and 1:6 is far too weak. 2 applications of render should be avoided at all costs. No you cant scratch it off the next day. Secrete/float the walls 1-2 hrs max after its applied. When floating the walls make sure the surface is sprayed with a fine mist to keep it moist. Small golf ball size blobs of render mix can be thrown on to fill any low spots whilst floating. And use a teflon float not a trowel. Be sure the wall prior to rendering is paint free & hosed down. the more water on the wall the better and if in direct sunlight work in small sections...2x1 mt
